It shows very aggressive behavior due to local invasiveness and is associated with various symptoms. Intracranial juvenile nasopharyngeal angiofibroma. Diagnosis of JNA is made by complete history, clinical examination, radiography, nasal endoscopy and by using specialized imaging techniques such as arteriography, computer tomography and magnetic resonance imaging.

Salvage Surgery in the Treatment aangiofibroma Local Recurrences of Several surgical approaches have been utilized for the removal of nasopharyngeal angiofibromas, including transnasal, transpalatal, transzygomatic, and transcervical accesses, in addition to lateral rhinotomy and mid-facial degloving, with or without extension to the upper lip or concomitant craniotomy 9.
A comparative study of surgical approches. Advanced lesions with orbital and intracranial extension are difficult to treat and may recur often. Craniofacial resection of advanced juvenile nasopharyngeal angiofibroma.
Thus, early diagnosis, accurate staging and adequate treatment are essential in the management of this lesion. Nasal cavity, paranasal sinuses, nasopharynx Other tumors Nasopharyngeal angiofibroma Author: Angioribroma tumor originates in the lateral wall of the nasal cavity, close to the superior border of the sphenopalatine foramen. The genetic alterations observed more often involve sex chromosomes.
